Next, process air, perhaps outer air, is passed through the first passages 2 while cooling air, for example outer air is passed through second passages 3 . With these actions, the absorbent 6 in first passages 2 adsorbs moisture in the process air and produces dry air from the first passages.

  • the temperature of the second passages 3 rises from the sensible heat of the heating fluid. This sensible heat travels to the first passages 2 , to cause desorption of the moisture contained in adsorbent 6 in the first passages 2 . At the same time, removal air is passed through the first passages 2 to carry out and discharge the desorbed moisture as steam.
  • the flow of the heating fluid to the second passages 3 is stopped.
  • a judgment of whether full desorption of the moisture retained by adsorbent 6 has occurred is made by measuring the humidity of the air exiting the first passages 2 . If the humidity of the air exiting the first passages 2 sufficiently falls, it is presumed that desorption of the moisture adsorbent 6 was fully carried out.
